If no consideration of any kind is paid for the conversion, then the shares so issued will be a "restricted security, " but  the holding period runs from the date the Subscriber loaned the money evidencing the Convertible Debenture to the Company.  The Convertible Debenture and shares underlying the Convertible Debenture may only be resold in compliance with Regulation S of the Securities Act of 1933 (Regs. 901-905).
